This starts off with shades of the real Tunisian beach attacks from 2015, when "Rapp" (Dylan O'Brien) and his girlfriend find themselves caught up in a shooting that ends in tragedy. Determined on revenge, he attracts the attention of the CIA with whom he ends up working before being sent to the ultimate ninja training camp under the auspices of veteran "Hurley" (Michael Keaton). Working with local intelligence, they identify their target and after a few predictably failed attempts, they are soon on the trail of the criminal who has plans of his own to exact revenge on the American imperialists. O'Brien is easy enough on the eye but the rest of this is about as derivative as it comes. Set piece action scenes ensue as day follows night, peppered with who to trust issues and the introduction of an unlikely enemy in "Ghost" (Taylor Kitsch) who has his own axe to grind with "Hurley". This is genre-fodder, and kills just short of two hours effortlessly enough (though the CGI at the end is really poor for 2017!). You are unlikely to recall it afterwards, and the plot has virtually no jeopardy so don't expect much here.
